Introduction: The New Paradigm in AI Development

In the rapidly evolving landscape of generative AI, developers face significant challenges when building complex applications. Traditional approaches often lead to monolithic, hard-to-maintain systems. The GenAI Processors Library emerges as an elegant solution – a lightweight Python framework designed for creating modular, asynchronous, and composable AI pipelines. This innovative approach transforms how we construct AI systems by introducing reusable processing units that can be chained, parallelized, and extended.

At its core, the library introduces the concept of a Processor – a fundamental building block that encapsulates a single processing task. Each Processor accepts a stream of ProcessorPart objects (data containers for text, images, or other content) and produces a transformed stream. This architecture enables developers to:

  • Create reusable AI components
  • Process content asynchronously at scale
  • Build complex systems from simple building blocks
  • Handle diverse content types uniformly

Core Architecture: Understanding Processors and Parts

The Processor: Fundamental Processing Unit

# Any class implementing this interface is a Processor
async def call(
  content: AsyncIterable[ProcessorPart]
) -> AsyncIterable[ProcessorPartTypes]

The Processor represents the atomic unit of work:

  • Encapsulates a single transformation or analysis task
  • Operates on asynchronous streams of data parts
  • Maintains a consistent input/output interface
  • Can be combined using intuitive operators (+ for chaining, // for parallelization)

The ProcessorPart: Intelligent Data Container

from genai_processors import content_api, streams

# Creating a processing stream
input_parts = ["Hello", content_api.ProcessorPart("World")]
input_stream = streams.stream_content(input_parts)

The ProcessorPart serves as the data vehicle:

  • Extends the standard genai.types.Part with enhanced metadata
  • Supports multiple content types: text, images, audio, custom JSON
  • Carries contextual information: MIME type, role, custom attributes
  • Enables uniform handling of diverse data formats

Key Technical Capabilities

1. Modular Design Philosophy

The library’s architecture enables unprecedented flexibility:

  • Component Reusability: Create specialized processors once, reuse everywhere
  • Intuitive Composition: Chain processors with processor1 + processor2
  • Parallel Execution: Run processors concurrently with processor1 // processor2
  • Streaming Interface: Process data as it becomes available
# Building complex pipelines
pipeline = (
    image_recognizer 
    + text_extractor 
    // sentiment_analyzer
    + report_generator
)

2. Gemini API Integration

The library provides native support for Google’s generative AI:

  • GenaiModel Processor: Pre-built integration for Gemini API
  • LiveProcessor Class: Specialized support for streaming interactions
  • Protocol Compatibility: Direct handling of Gemini input/output formats

3. Rich Content Handling

The content API supports diverse media types:

  • Automatic conversion between Python types and ProcessorPart
  • Metadata preservation throughout processing
  • Unified interface for text, images, audio, and custom data
  • Role management for conversation contexts

4. Extensibility Framework

Developers can extend functionality through:

  • Class Inheritance: Create custom processors by subclassing
  • Function Decorators: Convert regular functions to processors
  • Community Contributions: Share processors via the contrib directory
# Creating a custom processor
class CustomAnalyzer(Processor):
    async def call(self, content_stream):
        async for part in content_stream:
            # Custom analysis logic
            yield transformed_part

5. Asynchronous Performance

Built on Python’s asyncio framework:

  • Non-blocking I/O operations
  • Efficient resource utilization
  • Concurrent execution capabilities
  • Seamless integration with async ecosystems

6. Advanced Stream Management

The library provides utilities for:

  • Stream splitting and merging
  • Content batching and unbatching
  • Error handling in data flows
  • Backpressure management

Practical Implementation Guide

Installation and Setup

# Requires Python 3.10+
pip install genai-processors

Basic Usage Pattern

from genai_processors import content_api, streams

async def run_pipeline():
    # Create input stream
    input_data = ["Sample content", content_api.ProcessorPart("Another part")]
    input_stream = streams.stream_content(input_data)
    
    # Process through pipeline
    async for result in text_processor(input_stream):
        print(result.text)

Creating Custom Processors

Developers can implement specialized functionality:

class SentimentScorer(Processor):
    async def call(self, content_stream):
        async for part in content_stream:
            # Analyze sentiment
            score = analyze_sentiment(part.text)
            yield content_api.ProcessorPart(
                text=f"Sentiment: {score}",
                custom_meta={'original': part.text}
            )

Metadata Management

ProcessorParts carry contextual information:

part = content_api.ProcessorPart(
    text="Analysis text",
    mime_type="text/plain",
    role="user-input",
    custom_meta={"source": "user", "priority": "high"}
)

Error Handling Strategies

Implement robust processing pipelines:

class SafeProcessor(Processor):
    async def call(self, stream):
        async for part in stream:
            try:
                # Processing that might fail
                yield processed_part
            except ProcessingError:
                yield fallback_part
